Title: Asynchronous delta modulator - designed for adaptive digitalisation of analogue signals with reduced component requirements
Inventor: MATT HANS JUERGEN DIPL ING
IPC: H03M3/02
Filed: 1974-04-27
Abstract: The difference signal between the analogue signal's instantaneous value and a predictor signal serves as criterion for the polarity of the binary output signal. The input signal is applied through a first resistor to one input of a differential amplifier, to which the amplifier output signal is also applied through a second resistor, thus providing a positive feed-back with hysteresis. The amplifier output is connected through a predictor to its second input. The amplifier output signal is the required delta modulated signal. The hysteresis is controlled by the ratio of the two resistors. The predictor is a double integrating RC circuit, whose output signal matches the modulator input signal.

Title: PBX with dialling-standby signal receiver - receiver connected successively to exchange - transmission controls
Inventor: MUYSSEN JOHN DIPL ING
IPC: H04Q3/62
Filed: 1974-10-25
Abstract: The private branch telephone exchange has the dialling standby signal receiver connected successively to only those control elements characterising exchange transmissions and responding afresh after each connection. The dialling-standby signal receiver connection depends on the coding of an outgoing freshly engaged line and on a connection not having yet been made. The switching can be repeated in this manner until a ready-for-dialling code is present. The connecting follows only for those transmissions that are actually waiting for a dialling through possibility. The cyclic process itself and the series of cycle are effected by the same sensing control.
